Pelican has 115 584 09 02 for $21.75.

If the VIN block of your old tag is intact, stick it over a new tag and attach the new tag to the pillar. Is it held on by rivets as on an early W124?

In my case, I lost an A-pillar trim piece clip so the VIN tag is holding the trim piece in place

OT - it amazes me that on American trucks VIN relevant info is tacked to the door rather than the door jamb.
